Galpi - EPUB PDF Reader & TTS

From the moment you open a book until you close it, you will never see an ad.
An EPUB and PDF ebook reader with text-to-speech, PDF annotation and freehand ink, your own fonts, a home-screen bookshelf widget and fingerprint lock — features other readers sell as upgrades, all included.
No in-app purchases, no subscriptions, no paid version. Galpi is free.

■ No ads while you read or listen
No ads on the reading screen, while text-to-speech is playing, or while you annotate.
Ads appear only as a banner at the bottom of the library and, now and then, a full-screen ad when you close a book and return to the library.
Choose to watch one rewarded ad and those go away for three hours.

■ Text-to-speech that reads your books aloud (EPUB and PDF)
· Keeps reading with the screen off, with controls on the lock screen and in the notification
· The sentence being read is highlighted and pages turn by themselves
· Headset and Bluetooth buttons: previous sentence, next sentence, play and pause
· Sleep timer that finishes the current sentence before stopping, or stop at the end of a chapter
· Speed, pitch and voice selection, using the TTS engine on your device

■ PDF reader with annotations
· Highlight, underline, strikethrough, notes, bookmarks and freehand ink
· No limit on annotations, and your original PDF file is never modified
· Full-text search, page thumbnails, table of contents, pinch zoom
· Search and filter all your annotations and jump straight to each one

■ EPUB reader you can tune
· Seven themes including sepia, dark and pure-black AMOLED, plus paper textures
· Font size, line spacing, letter spacing, margins, paragraph spacing, indent
· Add your own fonts — import TTF or OTF files and use them for the text
· Two-column reading on wide or landscape screens (tablets and foldables)
· Auto page turn, turn pages with the volume keys, slide the left edge for brightness
· Tilt to turn pages, and assign actions to two-finger gestures
· Rename characters throughout a book, read-aloud included
· Send a word to your dictionary or translation app

■ Library, stats and backup
· Shows the books in folders you choose, with covers, continue reading, search and sorting
· Move or rename a file and you keep your place
· Reading stats and a daily goal — time with the book left open and untouched is not counted
· Backup and restore without an account — one file carries your progress, annotations and history
· Home-screen bookshelf widget and recent-book shortcuts
· Download books from public OPDS catalogs straight into your library
· Reading, annotating and backup all work offline
· Fingerprint and PIN app lock (it hides the screen; it does not encrypt your files)

■ Made Korean-first
Korean line breaking, Korean read-aloud clean-up, and character renaming that fixes Korean particles. The English interface was built alongside it, not bolted on.

■ Before you install
· DRM-protected books cannot be opened. Most books bought from online stores use DRM and must be read in that store's own app. Galpi opens DRM-free EPUB and PDF.
· TXT, MOBI, AZW3, FB2 and CBZ files are not supported yet, and there is no vertical scrolling mode yet.
· Scanned PDFs (images with no text layer) cannot be read aloud.
· No account and no cloud sync. Moving to a new phone? Use the backup file.
· Books are read from a folder you choose, and Galpi never sends your books, annotations or reading history off your device.
